The housing 1 is further provided with a passage 15 connected to the accommodating space 10, and the passage 15 is connected to an external circulation system not shown.
Referring to fig. 1 and 2, the magnetic disc 2 is located in the accommodating space 10 and disposed in the housing 1, a vibration plate 21 is fixedly disposed on the magnetic disc 2 facing the vibration wave transmitter 13, the vibration plate 21 includes an insulating elastic sheet 211 and a metal sheet 212, one side of the insulating elastic sheet 211 corresponds to the vibration wave transmitter 13, the other side of the insulating elastic sheet 211 is disposed with the metal sheet 212, and in this embodiment, the periphery of the insulating elastic sheet 211 is tightly fitted to the surrounding wall 11. The insulating elastic sheet 211 is further provided with a hollow portion 2110 for exposing a portion of the metal sheet 212, and a chamber 101 is formed between the insulating elastic sheet 211, the exposed portion of the metal sheet 212 and the shock wave transmitter 13. The magnetic disk 2 further comprises an insulating base 22 and a coil 23, the insulating base 22 is made of alumina material, the insulating base 22 is provided with two wire holes 221, the coil 23 is disposed on the insulating base 22 and two ends of the coil are led out from the two wire holes 221, and an insulating layer B covers the coil, so that the coil 23 is located between the insulating base 22 and the insulating layer B, and the insulation between the coil 23 and the periphery thereof is enhanced.
Referring to fig. 3, the chamber 101 is filled with a seismic conductive medium 3, and the seismic conductive medium 3 is circulated through the passage 15.
